Alameda and Contra Costa counties. W. E. Bryant. 

 Rare winter visitant. 



Haywards. Cooper. I shot a very perfect male April

Murphys, December, 1877, common; Marysville, Feb- 

 ruary, 1878, less common; Summit, October 1, 1885, 

 first specimen. In fall and winter it is not easily dis- 

 tinguished from Audubon's Warbler, and being much 

 less numerous than the latter is likely to be overlooked 

 in California. I shot a male in fine breeding plumage 

 at Stockton March 20, 1886. It had a companion, prob-

 fers about thirty feet from the ground, two of them were
